IPC: H01L29/417
Filed: 1999-06-01
Abstract: A thyristor device can be used to implement a variety of semiconductor memory circuits, including high-density memory-cell arrays and single cell circuits. In one example embodiment, the thyristor device includes doped regions of opposite polarity, and a first word line that is used to provide read and write access to the memory cell. A second word line is located adjacent to and separated by an insulative material from one of the doped regions of the thyristor device for write operations to the memory cell, for example, by enhancing the switching of the thyristor device from a high conductance state to a low conductance state and/or from the low conductance state to the high conductance. This type of memory circuit can be implemented to significantly reduce standby power consumption and access time.

Abstract: PROBLEM TO BE SOLVED: To provide a lighting fixture which prevents generation of damages on mounting of a lens on a lighting fixture body and realizes cost reduction while preventing deterioration of an appearance. SOLUTION: The structure is to satisfy the relation of L1>L2 when the length from a front end part P1 of a front opening of a lighting fixture body 1 to a front end part P2 of an engaging hole 16 is L1, and that from a front end part P3 of a front opening of the lighting fixture body 1 with a lens 2 mounted to a tip end P4 of a peripheral rib of the lens 2 is L2.  In mounting the lens 2 on the lighting fixture body 1, it becomes now possible to begin mounting it from a state where a lance 23 of a lance piece 22 is inserted and positioned inward from the end part of one side face of the lighting fixture body 1, by which, interference between the lance 23 and the front end part P1 of the body 1 is prevented from interfering each other, and therefore, a scratch or peeling off of a film formed on the inner face of the lighting fixture body can be prevented and also deterioration of an outside appearance of the lighting fixture can be prevented.
